Stochastic multi-objective optimal energy management of grid-connected unbalanced microgrids with renewable energy generation and plug-in electric vehicles
(2022-02-15)
Microgrids (MGs) contribute to the integration of renewable energy-based distributed generation (DG) units and electric vehicles (EVs) in a smart, secure, sustainable, and economic fashion. However, the unbalanced nature ...
Cooperative Regulation of Imbalances in Three-Phase Four-Wire Microgrids Using Single-Phase Droop Control and Secondary Control Algorithms
(IEEE, 2020)
Collaborative control of power converters operating in microgrids with unbalanced single-phase loads is difficult to achieve, considering that the voltages and currents have positive-, negative-, and zero-sequence components. ...

(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Collaborative control of power converters operating in microgrids with unbalanced single-phase loads is difficult to achieve, considering that the voltages and currents have positive-, negative-, and zero-sequence components. ...
Single-phase consensus-based control for regulating voltage and sharing unbalanced currents in 3-wire isolated AC microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
A distributed control strategy is proposed to share unbalanced currents in three-phase three-wire isolated AC Microgrids (MGs). It is based on a novel approach where, rather than analysing the MG as a three-phase system, ...
A Control Algorithm Based on the Conservative Power Theory for Cooperative Sharing of Imbalances in Four-Wire Systems
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 1986-2012 IEEE. A cooperative control scheme based on the conservative power theory (CPT) is proposed, which can share imbalances in three-phase four-wire droop-controlled systems. By utilizing the CPT, the balanced, ...
Experimental evaluation of a CPT-based four-leg active power compensator for distributed generation
(2017-06-01)
Four-wire microgrids (MGs) and distribution systems are inherently unbalanced with the presence of negative and zero sequence components in voltages and currents. In small autonomous systems, the imbalance, in addition to ...
Distributed control strategy based on a consensus algorithm and on the conservative power theory for imbalance and harmonic sharing in 4-wire microgrids
(IEEE, 2020)
A distributed control system is proposed which uses the Conservative Power Theory (CPT) and a consensus algorithm to share imbalance and harmonics between different converters in three-phase four-wire droop-controlled ...
Coordinated Control of Distributed Three-And Single-Phase Inverters Connected to Three-Phase Three-Wire Microgrids
(2020-12-01)
This paper explores the coordinated strategy named power-based control (PBC) to properly coordinate grid-Tied single-And three-phase distributed energy resources (DERs) in three-phase three-wire microgrids (MGs). By means ...
Multi-Purpose coordinated control of distributed energy resources in transactive AC microgrids
(Universidade Estadual Paulista (Unesp), 2021-09-22)
A contínua expansão do uso de recursos energéticos distribuídos (REDs), normalmenteconstituídos de fontes de energia renovável e/ou sistemas de armazenamento com seus respectivos inversores de potência, tem incorporado a ...
Co-otimização de fluxo de potência ótimo dinâmico baseado em preço com agendamento de reparos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2020-12-21)
The main objective of the electric distribution system operators is to supply energy to the
loads at the lowest generation cost over a given time horizon, anticipating sudden changes
in demand and generation, a problem ...
